Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for making tobacco smoke filters wherein the products have an elongated hollow inner member overwrapped with a conventional plug wrap, with an intermediate member inter-posed therebetween.  The apparatus comprises making smoke filters comprising:  a source of a first filtering material including a multiplicity of fibrous members; means defining a first elongated annular bonding zone; means for continuously feeding said first filtering material through said first bonding zone; means for feeding a bond activating agent into said first bonding zone and into contact with said first filtering material to bond said fibrous members of said first filtering material to each other at spaced contact points thereby forming an elongated, smoke-per-meable, inner member defining a tortuous path for passage of smoke therethrough; means for forming axially spaces sections extending across the interior of said inner member which offer at least as much resistance to passage of smoke as the material of said inner member to thereby form a multiplicity of axially spaced, discrete, inner cavity means within said inner member; a source of a second filtering material including a multiplicity of fibrous elements; means defining a second elongated bonding zone; means for continuously passing said inner member through said second bonding zone and defining an annular space around said inner member in said second bonding zone; means for continu-ously passing said second filtering material into and through said annular space in said second bonding zone; means for feeding a bond activating agent into said second bonding zone and into con-tact with said second filtering material to bond said fibrous members of said second filtering material to each other at spaced contact points thereby forming an elongated, smoke-permeable, intermediate member defining a tortuous path for passage of smoke therethrough surrounding said inner member; means for overwrapping said intermediate member with an overwrapping material so as to juxtapose portions of the inner surface of said overwrapping material with the exterior surface of said intermediate member to form sealed areas precluding passage of smoke thereacross; and means for transversely severing the resulting product at selected locations to form filter elements.

Abstract: ABSTRACT       A dry release transfer is disclosed in which the design layer is formed by printing one or more inks onto a carrier sheet, at least one of the inks being a photopolymerisable composition, and subjecting the design layer to ultra-violet radiation or an electron beam discharge in order to polymerise the photopoly-merisable ink.  By suitable selection of polymerisable components of the ink so that the photopolymerised ink has a high Young's modulus, a stress-resisting design layer is produced which will release readily from the carrier on mechanically stressing the carrier, e.g. by rubbing lightly with a ball-point pen.

Abstract: PACKET TRANSMISSION SYSTEM WITH VOICE SIGNAL PRIORITY     ABSTRACT        In a packet transmission system in which a plurality of kinds of telephone signals are packetized and transmitted, when a voice signal call is originated, a real channel is established for the voice signal call prior to a signal call other than a voice signal call, so that a transmission channel is occupied in each frame.  When the voice signal call is over, the transmission channel allocated to the voice signal call, is changed to a condition in which another call can be allocated thereto.  The system is useful for effective utilization of a packet communication network, without impairing the transmission quality require-ment for a voice signal call.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of operating a coke-oven battery with regenera-tive heat exchange between the gaseous combustion agents, in which method such properties of the gas supplied for heating, for ex-ample, its calorific value, pressure, density and humidity, as affect the quantity of heat evolved in combustion of the gas are measured continuously and a controller minimizes the effect of variations of such properties on oven operation, characterised in that, if a facility for regenerative change-over of the battery is so devised that each regenerative half-period can be broken down into a time when the burners are heating and a time when no gas is being supplied (pause), and if a final control facility is used which causes the change-over device to provide a desired breakdown as between the two times, the controller so acts on the final control facility that the duration of the heating time corresponds, having regard to the variations in heating-gas pro-perties, to a constant quantity of heat supplied to the battery in each regenerative half-period.

Granted: 1982-09-14
Abstract: ABSTRACT OF THE INVENTION            In a method for drying moist webs of paper or cardboard, the moisture profile is optimally equalized by first drying the paper web to a moisture content of 10 to 20% with conventional cylinder drying machines. Subsequently, capacitive high-frequency drying is performed to a moisture content of about 6 to 10%.  Drying to the desired final moisture content of, for example, 4% is carried out with a cylinder dryer.  The limits of use of the high-frequency dryer are given, among other things, by the cost of high-frequency energy and by the danger of breakdowns.

Abstract: SAFETY ASSEMBLY FOR A TOOL    FOR DRIVING FASTENERS        Abstract of the Disclosure A tool for driving fasteners includes a driver and a device for actuating the driver through a driving stroke.          The tool is operated by a trigger assembly that includes a manually actuated trigger pivotally mounted on the tool and a lever pivotally mounted at a first end to the trigger.          Also included on the tool is a safety assembly that before the tool can be fired must be actuated prior to actuation of the trigger.  The safety mechanism includes a push rod slideably mounted within the tool with a first end engaging a safety yoke and a second end adjacent the lever of the trigger assembly.  The safety yoke is slideably mounted on the nose of the tool and is adapted to extend below the nose of the tool to engage the workpiece upon placement of the tool onto the workpiece.   As the tool is placed against a workpiece prior to actuation of the trigger, the yoke and, thus, the push rod are moved upwardly until the second end of the push rod engages the lever placing the trigger assembly in an operative mode.  As the trigger is thereafter actuated, the lever is pivoted to actuate the tool and drive a fastener.  The safety assembly includes an engagement or locking element on the second end of the rod that locks the second end of the lever in an inoperative position if the trigger is actuated prior to the placement of the tool onto the workpiece.
